点击翻译按钮获取中文摘要

Saving energy and space, the system configuration of vibration isolating stand for transporting the injured using pleasure boat was investigated. First, it turned out that using the dynamic damper for active vibration isolating stand could suppress the actuator force into 40% compared with the pure active stand. Next, applying the mechanical snubber was investigated. It turned out that approximation mechanism of the absolute ceiling was effective in the saving the energy and the space. Finally, as a control system of the semi-active stand, it turned out that the sliding mode control with the describing function method was effective.
